4 Claims.

This invention relates to apparatus for use in covering heels and is herein illustrated as embodied in a cementing stand especially designed to facilitate the operations of cementing wood 5 heels and covers therefor preparatory to pulling the covers on the heels.

Wood heels are customarily covered to order for use upon shoes made in lots each containing various sizes. Accordingly, a lot of heels for a particular lot of shoes will contain heels of different sizescorresponding to the sizes of the shoes so that the heels will properly fit the shoes. In order to avoid undue waste of cover material, the covers are often cut in different sizes also, there being perhaps one size of cover for each two or three sizes of heels. As well known to those familiar with the art of heel covering, it is customary to apply cement both to the heels and to the covers of.

successive heel-and-cover lots, to arrange the heels and covers according to size on separate trays after being cemented, and to set the trays aside to allow the cement to become tacky before pulling the covers on the heels. Normally a substantial number of lots of heels and covers are cemented before any of the covers are pulled on the heels and often much confusion and loss of time is occasioned by the lack of any systematic handling, arranging and storing of the trays and the resulting difficulty in locating and bringing together heels and covers of the same heel-andcover lots. provision has been made heretofore for receiving and holding the numerous trays of cemented heels and covers an excessive amount of factory space has been required to accommodate them and the covers were liable to become displaced, soiled or otherwise rendered unfit fdr use.

One object ofthe present invention is to provide a cementing stand for use in connection with the operation of covering wood heels which will be of simple and rugged construction and well adapted to the needs of an operative who has to perform the cementing operations and wherein provision is made for overcoming the various dimculties above-referred to; Y

To the accomplishment of the above object the present invention provides. apparatus which, as herein illustrated, comprises a work bench adapted to support'trays of cemented heels and trays of cemented covers, a dip tank located at one 'end 7 of the bench for use in cementing heels, a rack at the opposite end of the bench for receiving the trays of heels and the trays' of covers, and other devices for use in handling the heels and covers including a device for dispensing cement Moreover, inasmuch as no adequate for application to the covers. Asalso illustrated herein, the rack is constructed and arrangedso as to permit trays of heels and trays of covers to be inserted from the front of the rack which is located adjacent to the front of the work bench 5 and to be withdrawn from the back of the rack which may be located adjacent to a station where the covers may be pulled on the heels by another operative. The above-described provision for holding the trays and facilitating their reception 1() and delivery insures against separation of the heels and covers of the same lots, eifects substantial economies of factory space, and saves both the time and energy of the operatives.

The invention further consists in features of 15 construction and combinations and arrangements of parts hereinafter described and particularly pointed out in the claims.

The invention will be explained with reference to the accompanying drawing, in which- 20 Fig. l is a front elevational view of my improved cementing stand;

Fig. 2 is a perspective view thereof; and

Fig. 3 is a fragmentary sectional view taken along the line III-III of Fig. 1.

As shown in the drawing, the cementing stand comprises a work bench ill for supporting heel covers while they are being coated with; cement f and for supporting (separately) the .trays upon which the heels and covers are arranged after'BO. being cemented, a dip tank I! which is secured .of the work bench area to provide additional tray '35 supporting surface, and a rack H which is secured to the right-hand end of the bench for receiving,

and holding trays of cemented heels and trays of cemented covers.

The illustrated structure is made of metal and, 40 as shown, the work bench itself comprises a rec'- tangular work-supporting portion, supported by legs l6, two of which are located at the righthand end of the bench andconstitute part of the rack l4, and a lower shelf 18 beneath the main 45 a work-supporting portion of thebench.j. The shelf I8 is divided by a vertical partition 20 into two compartments 22 and 24 for holding accessories 01 p p r, such as the. sheets 28, which may beemployed for the purpose of lining the boxes into which the finished heels are finally delivered. The self I8 is extended beyond the compartment 22 to support the cement tank I2. Beneath the compartment 22 the work bench is constructed as shown so as to provide a compartment 30 for the convenient storage of empty heel trays, such as the trays 32. The compartments 22 and 24 are closed at the rear of the bench and are open only at the front of the bench since the sheets of paper which they contain are inserted in the front by an operative who is stationedin front of the cementing stand, but the compartment 30 is open both at the front and the rear of the stand, thereby enabling the trays 32 to be removed from the front of the cementing stand and later, after the trays have been transferred to the station at the rear of the cementing stand, to be replaced in the compartment 38 by the operative at the rear of the cementing stand. The top or main work-supporting portion of the work bench I0 is of a size to provide ample space for supporting a single tray, such as one of the trays 32, for receiving cemented heels, or a single heel cover tray, such as one of the trays 34, shown in the rack I4. On the right-hand portion of the work bench is located a cementing pad 36 of rubber or other material which may be readily cleaned, the pad being adapted to hold a stack of heel covers while an operative manually coats the covers on one side with cement prior to laying them upon one of the cover trays 34 on the left-hand side of the bench I8. Behind the cementing pad 36 on the work bench space is provided for holding a cement-dispensing device 38 for supplying cement for application to the heel covers. The cementdispensing device 38 may advantageously be permanently secured in place upon the bench and supplied with the bench as a unitary part of the cementing stand. The cement dispensing device 38 embodies features of construction which are described and claimed in United States Letters Patent No. 2,017,990, granted October 22, 1935, upon application of E. J. Ray.

The work bench I0 is further provided with an upper shelf 48 which is supported above the rear of the work bench by means of uprights 4i, and is divided, by means of partitions 82, into separate compartments 43, 44 and 45. The com-- partment 43 is adapted to receive and support a water-dispensing device, such as the watering pot 66, for use in moistening absorbent pads contamed in the cover trays 3d. The compartment 44 is provided with means, herein illustrated as a clip 48, for holding heel order tickets or tags, such as the tag 50, in upright position so that the tags may be easily read by the cementing station operative. On the shelf 48, near the clip 48, there is also provided a flexible post 52 having attached thereto a pencil 54 for use in connection with a memorandum pad, such as the pad. 58, to note the sizes of heels to be ordered to replace heels which have been rejected for one reason or another from the lots being operated upon. The compartment 45 provides space for holding rejected heels, a group of such heels being shown at 88, and for receiving a receptacle, such as the can 62, which is provided with a tight-fitting cover for receiving the cement brush used in connection with the dispensing device 38.

The dip tank I2 of the work bench is secured upon or is made integral with a shelf 66 extending from the left-hand end of the work bench i0 and comprises a rectangular body portion 68 having a cover 10, hinged at I2 (Fig. 3) to the body of the able for the support of heel or cover trays.

tank, the cover being shown open in Figs. 1 and 3 and closed in Fig. 2. When the cementing stand is in operation the tank I2 contains liquid cement, for example latex, in which the heels are dripped before being laid upon the trays 32. To enable the heels to be conveniently removed from the latex the tank I2 is provided with a skeleton basket 14, the latter being provided with handles 16 by means of which the basket may be lifted to raise the heels above the level of the cement. The handles I8 are pivoted to the basket and are so constructed that when tilted outwardly, as shown in the drawing, they will engage the upper edge of the tank I2 and hold the basket in its elevated position to enable the surplus cement to drain from the heels and return into the tank. A paddle I8 for use in agitating the heels in the cement is detachably secured to the inside of the cover Ill by means of a spring clip 80 adapted to engage the handle of the paddle, and a supporting bracket 82 is arranged to support the paddle by engagement with its lower edge. When in raised or open position the cover 10 of the cement tank is tilted backwardly against a stop 84 arranged to support the cover at such an angle that the paddle will be located above the open top of the 'tank so that any cement contained thereon will drain from the paddle into the tank. When the cover is lowered, as shown in Fig. 2, the tank is closed to prevent evaporation of cement and the top of the cover is level with the surface of the bench I0 and serves to extend the area avail- At such times also the stop 84 cooperates with the uprights 4| in providing a back stop for heel and cover trays upon the bench and upon the extension of the bench provided by the closed cover 10 of the cement tank I8.

The rack I4 comprises two uprights 88, 88 which are formed as upward extensions of the legs [6 at the right-hand end of the work bench I8, and two uprights 90, 90 which are spaced from the uprights 88, 88 a distance substantially equal to the width of the heel and cover trays so as to permit the latter to be inserted between the two pairs of uprights. The uprights i are maintained in the spaced relation specified by means of horizontal tie rods 92. It will be noted that the legs I 6 at the right-hand end of the bench, which are, in fact, portions of the rack, cooperate with the other legs It in affording a firm support for the entire structure including the rack, the bench, and the dip tank.

Horizontal ribs or flanges 94 are provided for guiding and supporting the heel trays 32 and the cover trays 3 3, by engagement with the opposite lateral margins of the trays, the flanges being secured to the uprights 88, 88 and 90, 98. As shown. the flanges 9A are in the form of angle irons each being constructed to permit the trays to be inserted from the front of the rack, i. e., from the side facing an operative stationed in front of the cementing stand, and to be withdrawn from the rear of the rack. The flanges 94 on each pair of uprights are arranged in separated groups of four, each group being adapted to support a single tray of heels and three trays of covers. Provision is made for supporting three groups of trays, each group containing the heels and covers of a single heel-and-cover lot, and the several groups being segregated from each other. To facilitate the insertion of the trays in the rack the uprights 90 at the outer side of the rack are spaced apart a substantially greater distance than the uprights 88 and the upright 90 at the front of the rack projects forwardly .a substantial amount on station, thus conserving the time and energy beyond the corresponding upright 88. This construction enables an operative, in. transferring a tray from the workbench to the rack, to move the tray crosswise of the rack until an edge of the tray engages the inner side. of the foremost upright 90. This upright serves as agage to position the tray in vertical alinement with the tray-receiving spaces within the rack so-that the tray may be readily pushed back intofj place, without requiring any particular'care-on the part of the operative in registering the tray withthe receiving spaces in the rack. Inasmuch as none of the trays in the rack afe supported in positions below the level of the top of the work bench, it will be unnecessary for the operative at the cementing station to stoop down or bend over in transferring any tray from the work bench to the rack. In the lower portion of the rack l4 below the level. of the work bench is a compartment 96 for the storage of empty cover trays 34. Since each of the cover trays is supplied with a moist absorbent pad, it is undesirable to stack these trays on end and, accordingly, the compartment 96 is shaped to permit the trays to be disposed horizontally therein. As shown, a low platform 98 is provided at the bottom of the compartment 96 to receive trays and support them somewhat above the floor so that they will be kept clean. The empty cover trays may be conveniently stacked one above another on the platform 9,8. The compartment 96 is open both at the front and at the rear of the rack so that the cover trays may be removed from the front of the rack foruse by the cementing station operative and may be replaced in the rack from the rear after the covers have been removed from the tray by another operative who pulls the covers on the heels.

From the foregoing description it will be apparent that the disposed relation of the work bench iii, the dip tank l2, and the rack I4 is such as to enable an operative to operate in a convenient and expeditious manner to cement the heels and covers of successive heel-and-cover lots, to arrange the cemented heels and covers on trays, and to set the trays aside to permit the cement to become properly conditioned for the pulling of the covers on the heels. Furthermore, the arrangement is such as to enable the operative to perform all the above-mentioned operations without leaving the cementing stand. The operation of cementing the covers is further facilitated, as already described, by the fact that the working area of the bench l0 may be extended by closing the cover of the dip tank so that the upper surface of the cover will be at the level of the bench. This enables the trays of covers to be shifted or handled more conveniently thanwould be the case if the available supporting space for the cover tray were more restricted. Also, by making use of the increased tray supporting area thus afforded, it'is practicable after the rack I4 has been filled to its capacity to cement an additional lot of covers and to park these covers temporarily upon the supporting surface afforded by the supporting surface of the dip tank.

It is to be noted that the construction and arrangement of the parts of the cementing stand are such that, in addition to facilitating the cement-applying operations, the subsequent operations of pulling the cemented covers on the cemented heels are also facilitated, inasmuch as the pulling-on operative may remove the trays of heels and trays of covers from the rear of the rack I4,'which is to be located close to a pullingnew and. desireto secure by Letters Patent of the United States is:
